Can't wait to let you in on my favorite crowd-pleasing appetizer! These Roast Beef & French Onion Pinwheels always vanish first whenever I host. I stumbled upon this idea while longing for French onion soup flavors in an easy-to-grab party snack. What came out? These buttery, savory spirals that blend the yumminess of French onion soup with soft roast beef, all tucked inside flaky puff pastry!
The Magic Behind These Bites
What gets me most about these pinwheels is how fast they're ready! They seem totally fancy (welcome to looking like a pro host!), but they're actually dead simple to whip up. The mix of that rich French onion dip with gooey provolone is just heaven, and the pastry turns so perfectly crisp. Everyone thinks I worked forever making them, but between us, they're a total breeze!
What You'll Need
- Puff Pastry: Grab it from the store I've always got some waiting in my freezer!
- French Onion Dip: The key to amazing flavor here.
- Sweet Onions: Slowly browned until they're sweet and golden.
- Roast Beef: Tell your deli person to cut it extra thin.
- Provolone: Gets all wonderfully melty inside.
- One Egg: Gives you that pretty golden crust.

Insider Tricks
After tons of batches, I've figured out some shortcuts! Get all your stuff ready before touching that pastry it warms up fast and gets tricky! Don't forget that egg wash brush it's what makes them shine so nicely. And definitely use some parchment paper you'll save yourself so much cleanup grief!
Ways to Serve
They're best when they're just warm enough that the cheese is still gooey! Put a small bowl of extra French onion dip nearby for dunking folks absolutely love that. They work great with other finger foods, but honestly? Sometimes I just make a batch and call it dinner with a side salad!
Storage Tips
Nothing beats them straight from the oven, but if you somehow have extras (which hardly ever happens at my place!), just tuck them in the fridge. Warm them back up in your oven don't use the microwave unless you want soggy results! And here's a handy trick: you can make the entire roll ahead and keep it cold, then just cut and bake when guests arrive.
Tasty Swaps
These little gems work with so many different fillings! Sometimes I swap in ham instead of beef and it's fantastic. As for cheese? Go wild with your favorites! I've tried them with Swiss and loved the results. Throwing in some browned mushrooms makes another awesome version that everyone grabs.
Quick Answers
Yep, the frozen puff pastry from the store works perfectly I never bother making my own! Can't find French onion dip? Just use cream cheese with some seasonings. And if you're planning ahead, you can freeze these babies completely then bake them without thawing. They might need a couple extra minutes in the oven, but they'll come out just as tasty!

Frequently Asked Questions
- → Can these be prepared in advance?
- Yes, put them together and slice ahead of time, then keep chilled until baking. Brush with egg just before baking. They're tastiest when fresh and warm.
- → Why not use frozen puff pastry?
- Frozen pastry is hard to roll and usually cracks. Thawed pastry is soft and flexible — leave it at room temp for about 40 minutes.
- → How do I keep them from falling apart?
- Seal the edge tightly with the egg wash. Lay the seam side down for cutting, and chill briefly if the dough's too soft.
- → Can I switch up the meats and cheeses?
- Sure, use ham, turkey, or even salami. Cheeses like cheddar, Swiss, or mozzarella work great too!
- → What's the egg wash for?
